Definitions
- the present invention relates to a heat exchange bundle intended to constitute the thermally active part of a heat exchanger.
- the present invention also relates to a method for welding two sheets together by means of weld beads.
- the present invention also relates to a method for producing an elementary bi-plate module for a heat exchange bundle.
- the present invention also relates to a heat exchanger incorporating the heat exchange bundle.
- Tube and shell heat exchangers are the most common today. They consist of a bundle of parallel tubes in which a first exchange fluid circulates, and in means for circulating the second exchange fluid several times in succession transversely through regions of the bundle which are successively closer to the first fluid inlet. These exchangers are universally known, and their use for over a century in the industry has demonstrated their reliability. The manufacturing methods are also known, and accessible to countless companies around the world. They are relatively easy to be cleaned, which allows them to be used with fouling fluids.
- the profile defined by the interior of the tubes is the profile having the best thermal and hydrodynamic performance. Indeed, the ratio of exchange coefficient / pressure drop is better than any other profile, for high circulation speeds, and fluids with low viscosity (general case of gases).
- Plate heat exchangers have appeared more recently on the heat exchanger market (after the Second World War). They have made an important breakthrough, particularly in the food industry, in the form of an assembly of plates, sealed by flexible seals, which allows easy disassembly and quick cleaning.
- the plates most often have zigzag undulations ("herring bones") consisting of straight parts of a few centimeters, followed by a change of direction, as illustrated by GB-A-798 535 .
- This profile is particularly effective when circulation speeds are low, and the viscosity of the fluids is relatively high (case of liquids).
- this profile is less well adapted thermally to the case of gases.
- the ideal would be to be able to produce an exchanger combining both the compactness and lightness properties of the plate exchangers, and the good thermal and hydraulic performance of the internal tubular profile.
- US-A-4,029,146 proposes heat exchangers constituted by plates with rectilinear longitudinal corrugations assembled two by two to form individual modules defining longitudinal conduits inside them in which a first exchange fluid circulates. These modules are grouped into a bundle. The second fluid circulates in intervals formed by shims between the modules. The path of the second fluid is unsuitable, either from the point of view of heat exchanges or that of pressure drops.
- JP-A-58 128 236 describes a method for manufacturing a thermal module by welding and hydroforming. For this, two metal sheets are welded to one another along longitudinal lines which are parallel to one another and by a peripheral weld bead interrupted at two opposite angles of the module for the entry and exit of the fluid. Then pressurized fluid is introduced between the two sheets which deforms the structure by swelling between the weld beads so as to define on the one hand longitudinal channels between the longitudinal beads and on the other hand end collectors along the transverse sides, at each end of the longitudinal channels. To control the swelling of the module during the hydroforming phase, the module is placed between two fixed surfaces which limit the expansion of the module in the thickness direction. Such a module poses problems of implementation and efficiency in operation.
- FR-A-2 685 462 proposes to limit the welding of the module to contact points distributed over the surface.
- the structure thus obtained is not very efficient on the hydrodynamic and thermal level.
- the process indicated for arranging the ends of the bundle in platinum, by forming bent edges on each sheet, is complex. Bending non-planar areas of the sheet poses production problems.
- the object of the present invention is thus to propose an exchange bundle, a heat exchanger and production methods which make it possible to produce a heat exchanger which is optimized in terms of fluid and heat exchanges without causing any particular difficulties for its industrial realization.
- the heat exchange bundle comprising: - Modules each comprising two sheets welded to the laser along longitudinal lines defining between them first passages, of substantially tubular shape, for a first exchange flui ⁇ e;
- Positioning means for positioning the modules relative to each other so as to define between the modules second passages for a second exchange fluid; is characterized by distributing means, for distributing in a substantially equitable and / or symmetrical manner the flow of at least one of the first and second fluids between all the corresponding passages.
- the distributing means comprise, at at least one of the ends of each module, a transition zone which defines for the first fluid a first transition passage, having, according to the width of the module, a dimension progressively narrowed from the corrugated zone where are the longitudinal laser weld lines to an open end of the module.
- This transition zone has a dual role. In operation, it allows an equitable distribution of the first fluid in the longitudinal conduits of each module. During manufacture, it allows a transition between the area of the longitudinal conduits where the width of the modules is significantly reduced compared to the initial width of the sheets at the location considered, and the end of the modules where the width of these may be very close to the initial width of the sheets at the location considered.
- the distributing means may also comprise, at at least one of the ends of the modules: an end plate, also belonging to the positioning means, traversed by openings in each of which is fixed in leaktight manner a terminal orifice of one respective modules; and a connection box, fixed to the plate so that the interior of the box communicates with the first passages through the openings of the plate.
- the plate does not pose any particular difficulties of installation.
- the terminal orifices of the modules give access to the transition passages previously discussed.
- the plate may have in the width direction of the modules a smaller dimension than the modules, which allows access to the second passages, intended for the second fluids, on either side of the plate.
- the distance between neighboring longitudinal welding lines can be less than or substantially equal to 30mm.
- the method for joining two sheets by a laser weld bead in particular for manufacturing a heat exchange module for a beam, is characterized in that the weld is formed through a window of a pressing device which presses the two sheets in mutual contact during the formation of the weld.
- a comb-shaped presser is used comprising several parallel elongated windows, through which an elementary bead is formed for each longitudinal bead, and this for each position of the sheets between two displacements.
- the method for manufacturing a heat exchange module in which two sheets are joined by parallel longitudinal weld seams, and by an at least partially closed weld seam at each end, then a pressurized liquid is introduced between the sheets to separate the sheets from one another by hydroforming between the weld beads, is characterized in that the closing weld bead is formed at a distance from the end of the longitudinal weld beads so as to reveal a transition passage between the end of the module and the longitudinal conduits which form between the longitudinal weld beads.
- the transition passage constitutes an area in which the width of the module varies between a relatively little reduced value compared to the initial width of the sheets at the end of the module, and a more reduced value in the area of the longitudinal conduits.
- the blank can then be cut through the transition passage, for example by pressurized water jet, to preserve at least one transition passage in the finished module.
- the two sheets are placed between surfaces which limit the expansion of the module in the thickness direction, these surfaces defining for the module a lesser thickness in the area of 1 end of the module only in a main area covering most of the length of the module.
- surfaces which limit the expansion of the module in the thickness direction these surfaces defining for the module a lesser thickness in the area of 1 end of the module only in a main area covering most of the length of the module.
- the invention relates to a heat exchanger incorporating a bundle according to the first aspect, in a sheath whose internal volume communicates with the second passages. It is preferred that in service the fluid bathing the internal volume of the sheath and the second passages is that of the two fluids which is at the lowest pressure. Indeed, the modules obtained by hydroforming have better resistance to internal pressure than to external pressure.

- FIG. 12 is a partial longitudinal sectional view of a heat exchanger according to the invention.
- FIG. 13 is a schematic perspective view showing the suspension of the beam on bars.
- a heat exchange module is obtained by laser welding of two metal sheets 1 and 2.
- the initial shape of the sheets is rectangular in a central zone 8, then tapers into a trapezoid in each of two end zones 9, which have lateral cutouts 53.
- the width of the sheets 1 and 2 can range, for example, from 50 to 800 mm.
- the length of the sheets is limited only by the size of the means available to limit the expansion in thickness during hydroforming as will be said later. In practice, sheets of 10 m and more are possible.
- the thickness of the sheets can range from 0.5 to 1 mm. It is therefore very low, for mechanical and economic reasons as well as thermal.
- Welding comprises at least one peripheral bead 3 having an interruption 4 forming an orifice in the middle of one of the longitudinal ends of the sheets.
- the peripheral cord 3 has longitudinal segments 12 parallel and substantially the same length as the longitudinal cords 6. In each end zone 9, the peripheral cord 3 defines a transition zone 13 whose dimension measured parallel the width of the sheets 1 and 2 decreases progressively from the end of the longitudinal cords 6 to the interruption 4.
- the transition zone 13 in the example shown has the shape of two successive trapezoids, one of which is slightly convergent adjacent to the longitudinal beads 6 and the other more strongly converging, going as far as the interruption 4.
- the two sheets are joined to each other by laser welding points 14 produced under the form of circular or ovoid cords.
- Each transition zone 13 is composed of a region without weld points 71, adjacent to the break 4, of a region with close weld points 72 adjacent to the ends 11 of the longitudinal weld beads 6, and of a region 74 located between the previous two relative to the length of the sheets.
- Each cord 6 therefore has a different length from its neighbors.
- weld points are also staggered, but with more space between them. Lines in phantom 76, 77,
- the two plates 16 and 17 define between them a slot 19 whose width corresponds substantially to that of the sheets 1 and 2.
- the pressers 16 and 17 are, on the other hand, prevented from following sheets 1 and 2 longitudinally by means of a stop 21 (FIG. 4) secured to the frame of the welding machine.
- Pressers 16 and 17 have the configuration of a comb, that is to say that they have for each longitudinal weld bead 6 to be produced, an elongated window 22 or 24. There is therefore a series of upper windows 22 parallel and a series of lower windows 24 parallel, corresponding. For simplicity, only three windows 22 have been shown in Figure 3 and seven in Figure 5, but these windows may be more numerous. Each window 22 or 24 reveals the corresponding sheet 1 or 2 in the region where part of a respective weld bead 6 is to be produced. Each time the sheets 1 and 2 stop, an elementary cord 23 is formed through each upper window 22, either by a single head traversing each upper window 22 longitudinally one after the other, or by a multiple head capable to weld through multiple windows 22 at a time. Once the elementary cords 23 have been made through the windows 22, the sheets 1 and 2 move by a length corresponding to an elementary bead 23. The lower windows 24 serve to prevent the laser welding performing at the same time a welding between the sheets 1, 2 and the lower presser 17.
- the peripheral bead 3 and the welding points 11, 14 can be produced by following a similar procedure, by means of a presser provided with window (s) formed and positioned appropriately.
- the windows may consist of orifices having the relative arrangement corresponding to that desired for a group of weld points.
- the blank formed by the two welded plates is placed between two surfaces 26 and 27 having a well-defined spacing between them which corresponds to the thickness desired for the module in the central zone 8.
- the surfaces 26 and 27 have a sufficient size to completely cover the central area 8 of the blank.
- Surfaces 28 and 29 closer to one another define between them the smaller thickness desired for the end zones 9 of the blank.
- the surfaces 28 and 29 are defined by wedges 31 placed against the surfaces 26 and 27, which also extend over the end zones 9.
- a pressurized liquid for example water
- a pressure of for example 4 to 17 MPa in at least 4 interrupts the weld bead 3
- the other end can be closed or serve as another liquid injection point.
- the liquid causes the blank to swell by spacing the two sheets relative to each other between the weld beads and between the weld spots.
- the blank then takes a first thickness el relatively large in the central zone 8, a second thickness e2 thinner in the regions 71 and 74 of the end zones 9, and a third thickness e3 even thinner in the region 72.
- L 'thickness el corresponds substantially to the spacing between the faces 26 and 27.
- the thickness e2 corresponds substantially to the spacing between the faces 28 and 29 of the shims 31.
- the thickness e3 results from the large number of weld points in the region 72, or if necessary an additional thickness provided on a part of the shims 31.
- the hydroforming reveals longitudinal conduits 32 between the longitudinal weld beads 6 and, as illustrated by a tearing off, a transition passage 33 in the transition zone 13.
- the passage 33 communicates the longitudinal conduits 32 with the opening 4.
- the two sheets form on either side of the transition zone 13 of the ears 34 in which notches or notches 36 are formed by cutting 36 shown in dotted lines in FIG. 1. In FIG. 9, some of the ears 34 have been omitted to simplify the drawing.
- FIG. 2 shows that each region with close points 72 has the shape of an arc of a circle around the center 45 of the terminal orifice 40 (the reference 40 is not given in FIG. 2), and extends up to 'at each lateral edge of the transition zone 13.
- the line 78 passing through the ends 11 of the longitudinal weld beads 6 also has the shape of an arc of a circle around the center 45.
- this arc of circle has ends 79 bent in the opposite direction to the terminal orifice 40. This has proved to be favorable in order to avoid a difficulty in supplying the longitudinal conduits 32a adjacent to the two longitudinal edges of the module.
- the first fluid meets, in service, roughly the same resistance to flow or pressure drop in its path between the terminal orifice and each conduit.
- longitudinal 32 because the distance is the same as well as the number of weld points encountered.
- the flow velocity is about the same along this path because the cross section of the region 74 is about the same as the cross section of the region 72, which is thinner but wider.
- the terminal orifices 40 are fitted into correspondingly shaped openings 41 of an end plate 42 (FIGS. 9 and 11) which is common. to all the modules of the bundle to be produced and which has, parallel to the width of the modules, a dimension 43 less than the width of the modules.
- the terminal orifices 40 are welded, as illustrated in FIG. 9, in the openings 41, so as to fix the modules in a position where they are in contact or almost in contact with each other by the external ridges of the corrugations of the central zone 8, now wavy by the formation of the channels 32.
- a first exchange fluid symbolized by the arrow 44 in FIG.
- a second exchange fluid can penetrate into the second channels also of generally tubular shape substantially axial, which are formed between the corrugation hollows of the adjacent modules and between the contact or quasi-contact lines 98 ( Figure 9).
- the second fluid passes from each side of the plate 42, thanks to the reduced dimension 43 of the latter, and between the regions with close points 72 of the transition zones 13 of the adjacent modules, thanks to their reduced thickness, like this. is symbolized in the outgoing direction by the arrows 46.
- the arrows 46 are substantially axial.
- the regions 72 therefore form between them second transition passages which open laterally on each side of the bundle and communicate with the second channels.
- FIG. 12 and 13 illustrate a heat exchanger according to the invention comprising a sheath 59 whose rectangular profile corresponds to that of the bundle and which tightly encircles the bundle over its entire length.
- the beam is suspended with the channels 32 oriented vertically.
- At the top of the sheath 59 are fixed by welding two opposite bars 61 (see also FIG. 13) which project towards the inside of the sheath and are engaged in the notches 36 of the ears 34 of the modules to support the modules, and consequently the bundle, by suspension resulting from the support of the shoulders 62 forming the upper end of the notches 36 against the upper face of the bars 61.
- connection box 68 connected to a connection conduit 69 for the first fluid is welded so sealed, by its open periphery, with the periphery of the plate 42 to communicate the terminal orifices of the modules with the connection conduit 69.
- the connection box 68 has a generally semi-cylindrical shape with respect to which the plate 42 s extends substantially along an axial plane.
- a second connection box 91 of semi-cylindrical shape substantially coaxial with the box 68 but with a larger diameter is fixed to the upper edge of the sheath 59 and to the upper face of the bars 61 to close the end of the sheath 59.
- a connection duct 92 communicates the connection box 91 with the outside of the exchanger for the circulation of the second fluid according to arrows 93.
- connection conduit 69 passes through the wall of the connection box 91 in a leaktight manner.
- the lower end of the heat exchanger may have a structure similar to that which has just been described except that there is not necessarily any bars 61.
- the assembly shown in Figure 14 may constitute an exchanger, or be housed in a pressure-resistant enclosure.
- the enclosure comprises fluid circulation pipes, which are connected to the connection conduits 69, 92 for example by expansion bellows. It is then preferred according to the invention that the interior of the enclosure communicates with the path of that of the two fluids which is at the lowest pressure and that this fluid is that passing between the modules.
- the bottom external connection box can be omitted to establish communication between the downstream low pressure circuit and the interior of the enclosure.
- annular reinforcement weld 94 is aligned aligned with each end of the future terminal orifice 40 of the module.
- the welds 94 reinforce each module with respect to the concentration of tensile stress which can be expected in this area due to the overpressure which tends to tear off the modules relative to the end plate 42.
- Figure 1 shows that a drain line 96 has been reserved between each reinforcement weld 94 and the edge of the transition zone to avoid any retention of liquid in this zone if the exchanger must be emptied for cleaning, maintenance, etc.
